June 1967 QST carried an article "The 9TO Mark II Keyer." This keyer featured a "single dot" memory using a double paddle key. If the dash lever was held closed, and then the dot lever was closed, and both were held closed, the last dash would complete, and ONE dot would be inserted. Then dashes would be sent until the paddles were released.

I built this keyer and found it to be very easy to use. Since then, I have not seen any other keyer that had that single dot insertion feature.

If anyone knows of a modern keyer with a single dot memory, I would appreciate info. Thanks.

You're right. If both paddles are closed, with the dot slightly ahead of the dash, one dot is sent, followed by many dashes. If the dash lever closes ahead of the dot lever, the output is: dash, dot, dash, dash..... Almost 20 characters can be sent with one (almost) simultaneous squeeze of the paddles.

I don't think an iambic keyer can do this, especially at higher speeds.
